Abstract

Iteration is essential for generating value in design processes. However, not all iteration generates value. Iteration that can be eliminated without value loss is waste. Moving towards lean design requires a better understanding of both value generation and waste reduction. This paper contributes to the development of lean design by examining how waste can be reduced through elimination of negative iteration. Preliminary research findings are presented regarding such design management techniques as reduced batch sizing and set-based design. Future research is proposed.
